Improvement in nail-extractors



' UNITED S'I'A'I'Es PATENT OFFIon JAMES TYZICK AND HENRY W. ESKILDSON, OF NEW YORK, N.'Y.

IMPROVEM ENT IN NAlL-EXT RACTORS.

Speeifieation forming part of Letters Patent No. 82,568, datcd September 29, 1868.

To all 'whom it may concern:

Be it known that we, JAi/Lns TYzIcK and HENRY W. EsKiLDsoN, of the city, county,

and State of New York, have invented certain new and useful Improvements in Nail-Extractors and that the following is a full, clear, and exact description of the same, reference being had to the accompanyin g drawings, making apart of this specification, in which- Figure 1 represents a perspective view of the nailextractor, lying on its side. Fig. 2 represents avertical section through the same in the aet of extractin g a nail. Fig. 3 represents a cross-section through the shackle.

Similar letters of reference, where they occur in the drawings, denote like parts in all the figures.

Our invention relates to an instrument for drawing out driven nails, and is constructed in such a manner that it accommodates itself to any size of nail, and can be made of any cheap material, such as cast-iron or malleable iron. The griping-points, which are the only parts susceptible of abrasion, are made. of steel and removable, so that they can be replaced when worn out, in this manner producing a very cheap and efiicient nail-extractor.

To enable others skilled in the art to make and use our invention, we will proceed to describe the same with reference to the drawings.

A represents the lever, which is terminated at its upper end by a ferrule, B, in which is inserted the handle O, which can be made of any length, according to the leverage required. In the lower end of the lever A is a recess, into which is inserted the griping point D, which is made of steel or other'metal. lnthe rear of the lever A, and connected with it by means of the screw a, or its equivalent, is a grooved piece, E, into which plays the tongue b, formed on the lower part of the lever A, the grooved piece E having a slot, c, which allows the screw a and lever A to be moved up and down.

To the lower end of the piece E is hinged,

by means of the pin d, the combined shackle and fulcrum L, which has in its forward end an opening, into which is fitted the gripingpoint F, which is made of steel or other resisting metal. The after end of the shackle L is turned upward, and acts as a shoe and fulcrum for the lever A to operate through the open- 4,ing of the shackle, the griping-point being at the same time guided by the inner ridges or cheeks e formed on the shackle.

When it is desired to draw out nails with this instrument, the operation is as follows: The stationary gripin g point F is brought or driven close to or under one side of the head of the nail to be extracted; then the gripingpoint D is brought down into the Wood by means of the lever A and handle O, on the opposite side of the nail, guided as it is by the groove in the piece E and by the inner ridges or cheeks e, formed on the shackle, when, by moving the lever A and grooved piece E round the pin d, the two griping-points D and F are brought toward each other, and, clasping the nail, the latter is brought out by continuing to vibrate the lever A round the after end of the shackle, which then acts as a fulcrum for the lever A.

Having thus fully described our invention, what we claim therein as new, and desire to secure by Letters Patent, is-

An instrument for drawing driven nails composed substantially of the lever A and shackle L, with their griping-points D and F, and hinged or linked together by the slotted piece E, the whole constructed to operate in the manner and for the purpose herein described and represcnted.
